- Also migrates mock_data

**Why?**
The mr_widget_options_spec implicitly calls a setFavicon
utility. This method depends on `onload` beind called when
`src` is set.

Resolve "Validate actor/user against CODEOWNERS"

Closes #207927

matched against _any_ rule found in CODEOWNERS.

Exclude creation event from audit changes

See merge request gitlab-org/gitlab!26140

Fix issue import to accept export format

See merge request gitlab-org/gitlab!25896

We want to be able to export issues and then use that export file to
import the issues to another GitLab project.

Prior to this change, the format of the export file did not match the
structure of the file that the issue importer expects. This change
expands the importer to first look for the know export column names and
then fallback to positional values if they are not present.
